49. (2) Teflon is a polymer of tetra fluoro ethylene. It is used for coating articles and cookwares to

make them non-sticky. 50. (2) All proteins are not found in L-form but they may be present in form of D or L. 51. (3) One ‘s’ and one ‘p’ atomic orbital hydridized to give two equivalent hybrid orbital which are

known as sp hybrid orbitals and the angle between sp hybrid orbitals is 180 . Their spatial arrangement is linear.

52. (2) A bottle of dry ammonia and a bottle of dry hydrogen chloride connected through a long tube

are opened at the same time at both ends. The white ammonium chloride formed will be near the hydrogen chloride bottle because rates of diffusion of gases are inversely proportional to the square root of their molecular weights. Hence, rate of diffusion of ammonia is greater than hydrogen chloride.

60. (1) Higher the reduction potential more easily it is reduced. Therefore, the sequence of deposition

will be as : Ag, Bi, Pb, Fe

64. (2)

65. (3)

66. (3) Aromatic amine is always weaker basic than aliphatic amine. Further due to the presence of

electron withdrawing groups (such as phenyl group) the basic character of arylamine decreases. Therefore, diphenylaniline is the least basic among these.

21Mg O MgO2

24g 16g 40g

0.56 g 2O will react with 24Mg 0.56 0.84g16

Amount of Mg left unreacted = 1.0 – 0.84 = 0.16 g Mg Hence, Mg is present in excess and 0.16 g Mg is left behind unreacted. 75. (4) Potassium chloride is used in the salt bridge because K ' and Cl ions have the same

transference number. 76. (2)

77. (1) Pyridine is a monodentate ligand hence it is not a chelating agent. 78. (3)

79. (2) 3HNO is added to decompose 2Na S and NaCN otherwise 2Na S will give black ppt. of 2Ag S

and NaCN will white ppt. of AgCN which would interfere with the test of Halogens. 80. (4) 2NHCOCH is O, P-directing while all others (i.e. COOH, 3COCH , CN) are m-directing.

85. (4)

86. (4) Chloro fluorocarbons react with 3O and cause depletion of ozone layer in the upper

atmosphere.



87. (2) Be has full filled 2s-subshell 22s and therefore shows least tendency to accept an electron.

Hence, Be is the least stable. 88. (2) Drikold is solid carbon dioxide which sublimes without melting. 89. (4) 2

0TiF contains 4Ti ion ( 0d configuration) and 2 2Cu Cl has Cu ion ( 10d configuration) which are colourless species.
